I need to use four monitor (1920x1200) in extended desktop on my PC for stock trading. With my video card I can use two monitors, so I need something else for other two monitor.

This is my configuration:
Motherboard - ECS Manufacturer MCP61PM-HM
Video Card - GeForce 8400GS 256 MB DDR memory
Windows XP SP3

Expansion Slots
PCI Two (two available)
PCI Express x16 One (None available)
PCI Express x1 One (One available)


searching on this forum I've a found a veryhelpful 3D

I've built a PC for stock trading with 6 monitors. You can use any video cards (they doesn't have to be of the same type) and any MB with two PCI-E. I would even suggest you use a P965 or P35 with two slots, because the bandwidth won't affect the cards (one of the slots is only x4) they aren't to expensive, very stable and don't use a lot of power.

BTW: if you'll want to add more monitors in the future you can either get a special card like the Nvidia NVS440 or you can just add a PCI (not PCI-E) card.

nvidia quadro 280 pci
This card will allow for 2 monitors and you can just plug it into your PCI slot.
HOWEVER!
I'm not 100% sure if you can use the card you already have and this one at the same time. It's possible but I'm not making any promises.

A sure fire way to do it is to buy a motherboard with 2 PCI-E slots. Then you can run a CrossFire (Dual ATI Video Cards of the same type connected to each other) setup on 4 monitors.

the problem i that the user in the 3D linked don't say if everything was ok, so I don't know if it will really work :na:

thank's for the advice but I think it's less complicated a solution with only one videocard once I change the motherboard, like NVIDIA® Quadro® NVS 450...I do not understand so much about crossfire :D

I dont know what your budget is but you could get one of AMD's new HD6870's you can hook up 4 monitors to one card however it is 225$ and 2 of the monitors have to be plugged in to the display ports.

good alternative to NVIDIA Quadro NVS, I didn't know it and costs the half :) 
so I have to change the motherboard!

anyone knows if this is possible?

I've found this about AMD - HD6870
Interface Type PCI Express 2.1 x16

are you sure that this new card with PCI Express 2.1 x16 will work well with my old mother board's PCI Express x16?

The 6850 should work just as well. There are also some 5xxx cards that support four monitors. (5750, 5770) You do need to use the DP on them. I'm not sure you can use the cheaper single link DP to DVI with them. They are good for 1080, not sure about 1200.

Process would be to remove GPU drivers, shut down and replace the card. Turn it back on, load the AMD drivers and then setup your Eyefinity profile.

PCIe 2.1 16x is compatible with PCIe 16x

as far as what 4745454b said about the 5770/5750 you have to get a special edition of those cards to have them support 4 screens. the 6870 on the other has every card support 4 screens

I have one monitor with DVI/VGA, but without DP and three with DP/HDMI/VGA, it's ok

no problem about this?

No official problems. I've heard rumors of 2.1 cards not working in 1.0 slots. Enough rumors to make me buy from places with good return policies.

im thinking vincent vaga should be fine and if im wrong... just get it from newegg great prices and a great return policy :)

ok no prob hope this helped
December 30, 2010 12:27:55 AM

i was just noticing what 4745454b said about the 6850 working just as well as the 6870 and yes as far as performance it should however the 6850 only has one displayport on it and you need 2 to run your setup so it would have to be the 6870

I thought all 6 series cards supported 4 monitors?

Did a quick search, came up with this.

http://www.techpowerup.com/reviews/HIS/Radeon_HD_6950/4...

Quote:
The card has two DVI ports, two mini-DisplayPorts and one HDMI port...AMD has also introduced DisplayPort 1.2 support with their new cards which allows the use of a DisplayPort hub to connect multiple monitors, or daisy chain them together.


So I guess we're both right? You can do it, but you need a DP hub to do so. How much does that cost? If its more then $70 then your better off with the 6970.

Note that the reference Radeon HD 6800-series outputs include two DVI outputs, an HDMI output, and two mini-DisplayPort outputs. While the number of supported displays has increased, there has been a trade-off in that only one DVI output is dual-link. The DVI output below the exhaust port is a single-link limited to 1920x1080 resolution. In return, you're able to directly attach four monitors today: two DisplayPort and two using a combination of DVI and HDMI.
from this article I think it's supported also by 6850 so I don't need a hub, I'm right?
in the image below we can see two DP, one HDMI, one Dual Link DVI and one single link DVI

Eyefinity is even more convenient to use now. The 6850's video output options are two DVI, one HDMI, and two Mini DisplayPort ports—the 5000 series had only one full-size DisplayPort jack. And because AMD has upgraded to DisplayPort 1.2, you can connect to more than one monitor across one connector, either using specially designed hubs or by daisy-chaining displays. Combined with AMD's new $30 active Mini DisplayPort adapter, which was released in late August, this is a major benefit in terms of ease of use. Unfortunately, one of the DVI ports is now only single-link, which cuts down on the kinds of displays you can use, but since few people would hook up two 2,560-by-1,600 monitors anyway, this is probably a net win overall.

no that is a reference card photo right before the cards where released this is how the back i/o of a 6850 looks now:


and what a 6870 looks like:


the 6850 only has 1 display port unlike the two that the 6870 has. so yes like 4745454b said you can use ether card but the 6850 will need an adapter which im thinking will cost you around 50$ to get a good one and at that point with the resolutions that you want to run and the fact that after you get the adapter and the 6850 you are only slightly off the price of a 6870 which is a faster card and does not need an adapter.
so ya i think you should go with the 6870
